    摘要: An endoprosthesis includes an expandable tubular body defined by a plurality of struts. In some embodiments, the expandable tubular body includes a bioerodible metal that has at least a first surface region and a second surface region. The first and second surface regions can have different surface oxide compositions. In some embodiments, the first portion has a thermally altered microstructure and the second portion has a wrought microstructure. The thermally altered microstructure can be a cast microstructure comprising dendritic grains. The first portion forms at least a portion of an outer surface of the expandable tubular body. In some embodiments, the expandable tubular body includes iron or a bioerodible iron alloy and at least one surface of the expandable tubular body includes a substantially uniform coating of iron(III) oxide.

    摘要: A sealed lead-acid cell and positive plate for a sealed lead-acid cell are provided. The positive plate comprises a grid supporting structure having a layer of active material pasted thereto, the grid supporting structure comprising a lead-based alloy consisting essentially of lead, from about 0.02% to about 0.05% calcium, from about 1.5% to about 3.0% tin, and from about 0.01% to about 0.05% silver. A positive plate in accordance with the invention has excellent mechanical properties, and is satisfactory for use in a lead-acid cell.

    摘要: Automotive SLI lead-acid batteries are disclosed which are characterized by enhanced resistance to intercell connection corrosion, even when exposed to the current, relatively high under-the-hood service temperatures in use with recent model automobiles. The straps are formed from a lead-based alloy including from about 3.0 to 3.3% antimony, from about 0.04 to 0.07% tin, from about 0.04 to 0.07% arsenic and from about 0.014 to 0.020% selenium, the percentages being based upon the weight of the alloy.
